Significant events and approaches for the overall study
following participant enrollment, but prior to group assignment

Subjects aged between and including 6 and 16 weeks at the time of first vaccination received 2 doses of Rotarix™ vaccine, liquid formulation, at Day 0 and at Month 1. As part of the routine childhood vaccination according to the Expanded Program of Immunization (EPI) recommendations in China, subjects in this group also received 3 doses of Infanrix™ vaccine and 3 doses of the oral poliovirus vaccine manufactured by the Institute of Medical Biology of the Chinese Academy of Medical Sciences (OPV). The Infanrix™ and the OPV vaccines were administered independently of (Sub-cohort 1) or concomitantly with (Sub-cohort 2) the Rotarix™ vaccine. When administered concomitantly, subjects received the 3 doses of Infanrix™ vaccine at Months 1, 2 and 3, and the 3 doses of the OPV vaccine at Day 0, Month 1 and Month 2. The Rotarix™ and OPV vaccines were administered orally; the Infanrix™ vaccine was administered intramuscularly in the left anterolateral thigh.

Placebo Group

Subjects aged between and including 6 and 16 weeks at the time of first vaccination received 2 doses of Placebo at Day 0 and at Month 1. As part of the routine childhood vaccination according to the Expanded Program of Immunization (EPI) recommendations in China, subjects in this group also received 3 doses of Infanrix™ vaccine and 3 doses of the oral poliovirus vaccine manufactured by the Institute of Medical Biology of the Chinese Academy of Medical Sciences (OPV). The Infanrix™ and the OPV vaccine were administered independently of (Sub-cohort 1) or concomitantly with (Sub-cohort 2) the Placebo. When administered concomitantly, subjects received the 3 doses of Infanrix™ vaccine at Months 1, 2 and 3, and the 3 doses of the OPV vaccine at Day 0, Month 1 and Month 2. The Placebo and the OPV vaccine were administered orally; the Infanrix™ vaccine was administered intramuscularly in the left anterolateral thigh.
